Modular residual current devices Ex9L-H and Ex9L-N in two or four-pole design. Technology is based on the classical principle of permanent magnet and electromagnetic armature, providing full voltage independence of protective functions. Type AC, A, S, S+A, G and G+A are available for nominal currents ranging from 16 to 63 A. Nominal residual currents cover the values of 10, 30, 100, 300 and 500 mA. Circuit breakers comply with the requirements of the standards IEC/EN 61008-1.
The Ex9L-H series provides residual current devices with conditional short-circuit resistance of 10 kA.
The basic Ex9L-N series of residual current device are offered with conditioned short-circuit resistance of 6 kA.
